Ítem Modelo de asignación de compras a proveedores considerando su flexibilidad y probabilidad de incumplimiento en la entrega(Universidad Icesi, 2012-01-01) Ayala Cruz, Jorge; Ablanedo Rosas, José Humberto; Ruiz Torres, Alex JesúsSupplier selection is a critical process in supply chain management and business competitiveness. This article presents a decision-making model that optimizes allocation of demand across a set of suppliers considering expected losses associated with delivery defaults, purchasing costs, unforeseen costs of non-delivered supplies, and supplier management costs. An experimental and sensitivity analysis was carried out to study the behavior of the model with regard to key parameters. The results reveal that the proposed model is sensitive to these parameters and demonstrate the usefulness of the model to decision makers in this field.Ítem El cabotaje marítimo en la cadena de suministros agrícola de Puerto Rico(Universidad Icesi, 2016-07-01) Ayala Cruz, Jorge; Suárez Gómez, JorgeEl presente estudio examina el efecto multidimensional del cabotaje marítimo que regula el transporte marítimo entre los mercados de Estados Unidos de Norteamérica y Puerto Rico. El objetivo del estudio fue analizar los efectos que esta medida no tarifaria tiene sobre el sector agroindustrial en Puerto Rico. La metodología de investigación consistió de entrevistas semiestructuradas y análisis de datos secundarios de los rubros agrícolas de mayor importación. Los resultados obtenidos concluyen que es la interacción de medidas no tarifarias inherentes a la relación comercial entre ambos países que incide en la eficiencia y competitividad del sector agroindustrial en Puerto Rico.Ítem Revisión de la literatura sobre gestión de la calidad: caso de las revistas publicadas en Hispanoamérica y España(Universidad Icesi, Facultad de Ciencias Administrativas y Económicas, 2015-07-01) Ayala Cruz, Jorge; Ruiz-Torres, Alex J.; Acero-Chavez, José L.; Alomot, NelsonThe purpose of this study is to present a review of research on quality management in Latin-American and Spanish journals published between 2005 and 2013. The study considers managerial focused research written in Spanish or English. The classification of the research considers three elements: the research methodology, the type of application/business sector that served as the basis of the study, and the specific quality management tools/topics addressed by the study. The analysis reveals that although there is significant interest in research related to international standards and the implementation of quality management systems, subjects such as quality management systems based on six sigma methodologies have not received much attention. The study concludes with a discussion of future areas of high potential research that have not generated much discussion.
